IPhone 7 Audio Not Working

If you hear no sound or distorted sound from your iPhone, iPad, or iPod touch speaker - Apple Support

Not receiving tones associated with text, messages and e-mails. My ringer works fine for actual phone calls and all of my settings appear correct. However, when I push on the side volume buttons a "ringer" window opens that should show the volume level but instead the little bell icon has a "\" overtop of it. Thus it appears as if the ringer has been turned off.

I can find no other volume/ringer changer or silencer that could be causing this problem.
